1080 CHAPTER 74: IS-IS CONFIGURATION COMMANDS
Description Use the preference command to configure the preference for IS-IS protocol.
Use the
undo preference command to restore the default.
By default, the IS-IS protocol preference is 15.
If a routing policy is specified in this command, the preference (if any) set by the
routing policy applies to those matched routes. Other routes use the preference
set by the preference command.
When a router runs multiple routing protocols at the same time, the system will
set a preference to each routing protocol. If several protocols find routes to the
same destination, the route of the routing protocol with the highest preference is
selected.
Examples # Configure the preference of IS-IS protocol as 25.
<Sysname> system-view
[Sysname] isis
[Sysname-isis-1] preference 25
reset isis all
Syntax reset isis all [ process-id | vpn-instance vpn-instance-name ]

Parameters process-id: Clears the data structure information of an IS-IS process numbered
from 1 to 65535.

named with a string of 1 to 31 characters.
Description Use the
reset isis all command to clear all ISIS data structure information.
No data structure information is cleared by default.
This command is used when the LSP needs to be updated immediately. For
example, after performing the area-authentication-mode and
domain-authentication-mode commands, you can use this command to clear
old LSPs.
Related commands: area-authentication-mode, domain-authentication-mode.
Examples # Clear all IS-IS data structure information.
